Let me clarify it's 10,000 watt continuous 18,000 surge. I use 2/0 welding cable to the batteries which are close. You don't need that size to run that winch. A 2000 watt is plenty if it runs off a wall 120v wall recept. I just a 2000 for $50. Use a quick connect like on a snow plow leave the invereter behind the seat in a bag. & you always have 120v power for tools winches,etc without the hassle of a generator.
